中文摘要	作为热河昆虫群的重要组成部分,义县组昆虫化石内容独特、丰富,共16目95科201属271种.根据目前已发表的化石资料,本文列举了冀北、辽西义县组昆虫化石以及与昆虫伴生的其它动植物化石.通过对其生物学和生态学特性的分析,初步建立了冀北、辽西义县组生态系统结构关系图,并恢复了它们所代表的生态环境.结构关系图显示该生态系统相对稳定,可能处于群落发展的稳定时期.该地区整体上为温暖湿润的气候环境,同时存在季节性干旱一半干旱的小气候环境.有丰富且宁静的深水湖泊,周围还有其他形式的水体环境,如沼泽和浅水环境;附近有高山存在,且海拔在800 m以上,高山上有湖泊,山间有溪流;土壤营养丰富且水分比较充足,适宜多种动植物生存.
英文摘要	Various unique fossil insects, including 16 Orders 95 families 201 genera 271 species, which are the most important members of the JehoL Entomofauna, have been collected from the Yixian Formation in Northern Hebei and Western Liaoning. Insects, associated animals and plants are enumerated here according to the publications. Hypothetical structure of ecosystem is preliminarily established, and also their environmental settings are reconstructed, by analysing their biological and ecological characteristics. The hypothetical structure shows that the ecosystem was relatively stable and this community may be in its stable stage. Overall, the climate of this region at that time was warm and humid, while there was seasonal arid and semi-arid climate in micro-environment. There were plenty of quiet deep-water lakes, while other water bodies existed around the lakes, such as swamps and shallow water environment; in the vicinity of water, there were mountains with the higth at least 800 m and alpines lakes and streams. The soil was nutrient and moist enough for a variety of plants, insects and other animals to survive.
